Patent CA-2269160-A1 (CA)
Title: Differential pressure switch having an isolated hall effect sensor
Inventor: KRUEGER RONALD R
IPC: H01H36/00
Filed: 1999-04-15
Abstract: A differential pressure switch comprising an enclosure including a peripheral wall and a solid one-piece non-perforate partition wall that is integrally attached to the peripheral wall around the entire perimeter of the partition wall. The enclosure includes a sensor chamber located on a first side of the partition wall and a fluid cavity located on a second side of the partition wall. The partition wall and the integrally attached peripheral wall seal the sensor chamber in fluid-tight leak-proof isolation from the fluid cavity. A flexible diaphragm is located within the fluid cavity and forms a low-pressure fluid chamber on one side and a high-pressure fluid chamber on a second side of the diaphragm. A magnet is located in the fluid cavity and is coupled to the diaphragm such that the magnet changes position in response to movement of the diaphragm. A Hall effect sensor is located in the sensor chamber. The sensor is adapted to sense the magnetic force generated by the magnet and thereby detect the distance between the magnet and the sensor. The sensor indicates when the magnet is located a predetermined distance from the sensor such that a predetermined differential in pressure exists between the pressure of the fluid in the low-pressure fluid chamber and the pressure of the fluid in the high-pressure fluid chamber.

Title: Cardboard-made spool assembly for pintle
Inventor: CORRIVEAU ANDRE
IPC: B65D85/04
Filed: 1999-04-29
Abstract: Disclosed is a spool assembly for a pintle or any other kind of wire element. This assembly includes a spool on which the wire can be stored, this spool being annular in shape and devised to define a radially outwardly open rim in which the wire can be wound. It also includes a casing shaped as a "pizza box" and sized to receive and enclose the spool. The casing has two opposite main walls and a large opening in the middle of at least one of the main walls to give manual access to the spool. The casing also has side walls and an outlet in one of its side walls to allow the wire wound on the spool to exit from the casing. Both the spool and casing are made of rigid cardboard, thereby making the assembly cheap to manufacture and easy to dispose off. Preferably, the spool assembly may further include a "brake" also made of cardboard, which can be inserted into corresponding holes provided in the main walls of the casing so as to interfere with the spool and to prevent it from rotating backward. Teeth may be provided on the periphery of the spool to cooperate with the brake and thus to achieve the requested prevention of rotation of the spool in one direction only.

Title: Process for the transmission of signaling and control information for wavelength-division multiplex networks for optical, fiber-bound information transfer
Inventor: DASSOW HEIKO
IPC: H04B10/27
Filed: 1998-05-11
Abstract: The invention relates to a process for the transmission of signaling and control information for wavelength-division multiplex networks (1) for optical, fiber-bound information transfer in digitized form, the signaling and control information being transmitted via the same optical channel, particularly with the same wavelength, as the user information, but being coded and decoded independently thereof, with the result that the control and signaling information can also be accessed independently of the user information. The use of a time-division multiplex process allowing the different coding of user information and control information makes it possible considerably to reduce the technical complexity of passive optical network elements with regard to the routing of the signaling and control information. The process according to the invention permits the simple, low-cost and transparent transmission of signaling and control information in optical WDM networks.
